Step-by-step explanation:

Answer:
-3
Step-by-step explanation:
To do this you just have to do the slope formula which is
then plug in the numbers so you get
which would
get you which can be reduced to -3 so that would be the answer
For perpendicular lines m2 = -1/m1, i.e. the product of the two slopes equals -1.
x - 5y = 3
5y = x + 3
y = 1/5 x + 3/5 => slope = 1/5
m2 = -1/(1/5) = -5
Equation of a line containing point (-4, 6) with a slope of -5 is
y - 6 = -5(x - (-4))
y - 6 = -5(x + 4)
y - 6 = -5x - 20
5x + y = -20 + 6
5x + y = -14
Step-by-step explanation:
v=Ah
A=9×12
= 108
then, v=108×8
